DEVICE FOR SECURING SPINDLES TO SHAFTS.

Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed May 17,1907. Serial No. 374,239.

of New York and State of New York, have invented a certain new anduseful Improvement in Devices for Se curing Spindles to Shafts, of whichthe following is a specification.

The invention is a device for attaching a spindle to an axle or shaft sothat it will be coaxial therewith and firmly secured thereto. A spindlethus aflixcd may be used, for example in connection with car axles foractuating axle lubricating mechanism, or speed recording mechanism, andin connection with shafts in general for transmitting motion to gearingwhich it may not be desirable to drive directly from the shaft itself.

In the accompanying drawingsFigure 1 is an end view of a car axleshowing my device in place. Fig. 2 is a section on the line at x of Fig.1, showing the device with the knife edge flanges on the resilient barbearing on the face of the axle, and Fig. 3 is a similar view showingthe disk flange seated 011 the end face of the axle and said knife edgesentering the metal of said face.

Similar numbers of reference indicate like parts.

1 is the end of a car axle having the usual centering opening 2. O11 theinterior of this opening 2, 1 form a screw thread of any suitable means.This can readily be done while the axle is in place under the car andwithout removing said axle, by any convenient hand tapping device.

The'spindle has a cylindrical outer portion 3 and an inner threadedportion 4. Integral with said spindle is a disk 5, having a polygonalshouldered projection 6 to receive a wrench. At its outer periphery saiddisk has a flange 7. On the spindle and adjacent to the disk 5 is alocking bar 8 of spring metal the ends of which are preferably benttoward the axle face and extend through the recesses in the disk flange7. On each side of each end of bar 8 are formed knife edge flanges 9.The bar 8 is rigidly secured on the spindle by any suitable means, as byraising a chip of the metal of the spindle and riveting or crowding thesame upon said bar as indicated at 10, Figs. 2 and 3.

In securing the device in place, the threaded end 4 of the spindle isinserted in the threaded opening 2 and the spindle isturned by a wrenchapplied to projection 6, until the disk flange 7 bears upon the end faceof the axle. As the knife edges 9 meet said face before the flange meetsit (see Fig. 2), it is obvious that when said' flange finally seatsitself on said face, the spring bar-8 will have yielded and by itsresiliency will be pressing the knife edges 9 against said face. Theknife edges are to be tempened hard, so that a few blows of a handhammer delivered upon the bar 8 will drive them into the metal of theaxle face, as shown in Fig. 3, thus looking the spindle and preventingits rotation.

The special advantage of this device is the ease with which it can beapplied to any shaft or axle already having a central centering openingin the end, since all that 18 necessary is to tap the thread on theinterior of the opening. No special holes are cut and there is no needfor dispacing shaft or axle from its usual or working position.

I claim:

1. The combination of a spindle having a threaded end, and, fast on saidspindle, a flanged disk and a resilient bar having a knife edge flange,the said bar extending through an opening in the flange of said disk.

2. The combination of a spindle having a threaded end, and, fast on saidspindle, a flanged disk and a resilient bar extending through an openingin the flange of said disk and having at its end a knife edge flange.

3. The combination of a spindle having a threaded end, a flanged diskformed integrally with said spindle, and a resilient bar, rigidlysecured on said spindle and in proximity to said disk, extending throughopenings in the flange of said disk and having, at its ends, knife edgeflanges.

4. The combination of a shaft having a central threaded recess in itsend face, a spindle having a threaded end constructed to be received insaid recess, a flanged disk on said spindle, a resilient bar on saidspindle having its ends extending through openings in the flange of saiddisk and knife edge flanges on the ends of said bar constructed to meetand be held against the said end face when said spindle is in place insaid recess.

In testimony whereof I have affixed my signature in presence of twowitnesses.
